Subject: [PATCH 0/9] perf_counter patches
Date: Sat, 28 Mar 2009 20:43:59 +0100 [thread overview]
Message-ID: <20090328194359.426029037@chello.nl> (raw)
This set fixes 2 problems I found while going over the perf_counter code.
- the delayed wakeups were incomplete (and broken on x86)
- update_userpage() wasn't used properly
It also adds tracking of the mmap() data so that we can profile userspace.
I also folded in Paulus' pending patches (I had to fix up a few conflict,
please double check).
Finally, the writable control page patch... still not convinced we need that.
